SLIP-JOINT FOR SHEET-'VIETAL CORNICES, PIPES, 81,0.

SPECIFICATION forming part of Letters Patent No. 415,224, dated November 19, 1889.

.To all whom it' nmz/concern.

Be it 'known that I, JOHN SMITH, ot' Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Slip- Joints for Sheet-Metal Cornices, Pipes, dsc., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in joints for metallic cornices, spouts, gutters, pipes, ttc., and it has for its object to provide a simple slip-joint, formed integral with one end of each section of the cornice, gutter, or pipe, to receive the plain end of the adjoining' section; and, furthermore, it has for its object to so arrange and construct the said joint that it will form a bracket which will be ornamental in appearance and will strengthen the structure.

lVith these objects in view the invention consists in a certain novel 'construction and arrangement of parts, fully described hereinafter in connection with the drawings, and specifically pointed out in the claims hereto appended.

In the drawings, Figure l is an end view of a cornice constructed in accordance with my invention. Fig. 2 is a perspective View of the same. Fig. is a perspective view of a portion of a spout or gutter with its sections constructed with the improved joint. Fig. 4 is a detail perspective view of a supportinghook, which is used in connection with the improved joint to support drain-pipes. Fig. is a vertical central sectional view on line 0c of Fig. 0 of a drain-pipe embodying my invention, and showing the supporting-hook applied thereto in the operative position, and Fig. G is a top plan view of the same.

In the construction of my invention I provide one end of each section of the cornice, gutter, or pipe with a groove, which is formed by doubling the metal upon itself twice, the other end of each section being left plain or straight to fit in the groove on the adjacent end of the adjoining section.-

In Figs. l and 2, A A represent sections of a cornice, and one end of each section is doubled on itself to form a loop 7.1, and again doubled on itself to form the groove B, the said groove being formed by the free end of flange Zbeing removed slightly from the inner surface of the loop 7.: to form a space. Close to the loop 7i: the material of the cornice is doubled twice upon itself to form the double loop m, and the portion of the cornice which connects the loops m to the loop k forms a plain or iiat surface 7L. A series of these plain surfaces corresponding to the corrugations in the cornice combine to form a bracket or brace H, which strengthens the cornice at the joint and renders the structure iirm and rigid. Thus the brackets are formed by the connecting portion of metal between two oppositely-extending loops, the free end of the section being extended and doubled to form a groove to receive the adjacent plain end of the adjoining section.

In Fig. 3 one end of each section of the gutter is doubled on itself in the same manner as above described to form the loop 7c, the free end or iiange l, with the intervening space or groove B and the double loop m, the connecting portion of metal between the loops k and m forming a fiat surface 71., which extends entirely around the gutter to form a bracket IMI, as shown; also, in Figs. 5 and G is shown a drain-pipe, one end of each section of which is doubled on itself in the same manner as above described to form the loop k, free end Z, and intervening groove I5, the double loop m, and the plain connecting-surface h, which forms a bracket Il.

The supporting-hook E, which is shown in detail in Fig. 4 and in the applied position in Figs. 5 and G, consists of a plate F, having an upstanding ear 'i to engage the groove B, and the shank c, which is adapted to be driven into the wall of a building. The outer surface of the plate F is provided with rosettes l b b in imitation of nail-heads.

To unite the sections A A of the cornice, the sections D D of the gutter, or the sections GG of the drainpipe,it will be seen that it is simply necessary to insert the plain end C of one section in the groove B on the adjacent end of the adjoining section, no nails, rivets, or solder being necessary to hold said sections together. The bracket or brace, which is shown in connection with the sections of the cornice, dce., is integral with the same, and as no cement or solder is employed in connection with sections all danger of the sections becoming detached or disconnected is avoided.

IOO

Having thus described my invention, I claiml. A section of a sheet-metal cornice, gutter, orpipe having one end plain and proyiided at the other end With oppositely-extending loops m and k, connected by a plain portion h, and the free end or iange Z, which forms with the loop la a groove B, substantially as specified.

2. A section of a sheet-metal cornice, &c., having one of its ends doubled upon itself to form. the oppositely-exte'ndingloops m and 7c, the outer or exposed sides of which are extended to form the plain connecting portion h, the free end of the Section projecting beyond said loops, substantially as specied.

3. The joint for metallic cornices, dac., consisting of integral loops m, adjacent loop k, connected to the loops m by a plain portion h, and the free end or flange Z, doubled on the loop 7c and removed slightly therefrom to form a groove B, substantially -as speciied.

In testimony whereof I affix my signature in presence of two Witnesses.

JOHN SMITH.
